Graphs of Trig Functions

Today we learned about graphing trig functions. First we learned how to graph them then we found out the domain(side to side), range(up and down), the zeros, the period(how many times the circle repeats or on a graph, horozontally.or 2pie.) and amplitude( the measure from the x axis to the top of the curve).The graphs for cosine and sine are the same except for the cosine graph is shifted over and the tangent is way different because its equation is y/x. I understood the concept.
